Most toiletry advice starts with the bag. That puts the product ahead of the two things that decide whether you need one: where you are flying from, and what you are actually carrying.
Step 1: Check the liquids rule for every airport on your trip
There is no single global rule. Screening rules differ by country and sometimes by airport or terminal. The table summarises the cited guidance reviewed for this guide on 15 October 2026. Confirm your exact route close to travel; permission at one checkpoint does not settle the next.
Swipe horizontally to compare all columns. Keyboard: focus the table and use the arrow keys.
| Screening location and source | Ordinary toiletries starting point | Exceptions and route checks |
|---|---|---|
| UK — GOV.UK | Most airports: containers no larger than 100 ml. Some allow containers up to 2 litres. Where a separate bag is required, use one transparent resealable bag holding no more than 1 litre. | Medical, dietary, infant and duty-free exceptions have conditions. Check departure, connection and return airports; a separate bag is not required everywhere. |
| EU — European Commission and departure airport | General Commission guidance: containers up to 100 ml in one transparent resealable 1-litre bag. Specific approved screening installations can permit larger containers. | Do not infer permission from “new scanners” alone. For example, Prague publishes different rules for Terminals 1 and 2. Check the actual terminal and all later screening points. |
| US — TSA rule as published by SEA Airport | Containers up to 3.4 oz (100 ml), all fitting in one clear quart-sized zip-top bag, one bag per traveller. | Medication and infant/child nourishment exceptions exist. Check current TSA and airport instructions for the item. |
| India — Air India’s restricted-baggage guidance | Air India specifies containers up to 100 ml in one transparent resealable bag up to 1 litre. | This is the airline’s published guidance, not a claim about identical national implementation. Confirm the operating airline and airport’s current rules and exemptions. |
| Canada — CATSA | Containers up to 100 ml/100 g, all fitting in one transparent resealable bag up to 1 litre; one bag per passenger. Take it out at screening. | Declared medical and infant items have specified exemptions. Check CATSA’s list and the rules at subsequent screening points. |
| Australia — Home Affairs | Where the international-flight restrictions apply: containers up to 100 ml/100 g in one transparent resealable bag. Its sealed perimeter must not exceed 80 cm, for example 20 × 20 cm. | Covers the specified international/transit situations, including domestic legs departing an international terminal; most domestic flights are excluded. Medical/infant exemptions and duty-free conditions apply. Aerosols need a cap or locking device. |
For any other country, check the national security authority.
What to check for your trip
- Your departure airport, and your terminal if the airport publishes terminal-specific guidance.
- Every airport you will pass through, including connections and the airport you return from. Rules can differ in each direction. Where they differ, pack to the strictest rule on your route.
- Anything bought airside or duty-free. Keep sealed bags sealed, and keep the receipt, as the authority requires.
- Essential medicines and baby feeding items. Exceptions exist but differ by authority, as the table shows. Check whether you must declare them.
- How current your information is. This guide’s rule summary was reviewed on 15 October 2026. Check again close to travel.

Step 2: Decide what goes in the kit
The same bathroom routine can be carried four ways.
Swipe horizontally to compare all columns. Keyboard: focus the table and use the arrow keys.
| Approach | When it fits | The catch |
|---|---|---|
| Decant into small containers | Carry-on only, short or medium trips | Containers must meet your airport’s size limit. No container is guaranteed leak-proof; judge a product’s leak-resistance by what its maker claims and shows |
| Full-size | You are checking a bag, or the airport’s rule allows it | Weight and volume. Check your airport before assuming it is allowed |
| Buy at the destination | Longer trips, or items you can easily replace | Availability, cost, and whether you are happy with unfamiliar products |
| Solid or non-liquid formats | Where they suit your routine | Whether an item counts as a liquid, gel or paste for screening is decided by the security authority, not by the packaging. Check borderline items |
Essential medicines and baby feeding items often have their own exceptions to the size limit, and they differ by authority (see Step 1). Check them separately rather than decanting them to fit.
Dry tools such as a toothbrush, floss or a comb are not what the liquids rule is about. If a razor is in your kit, check the security authority’s rules on sharp items separately.
Step 3: Organise it
The two-pouch option. A common method is a clear, liquids-only pouch for anything wet and a second fabric or zip pouch for dry tools. This is one optional method, not a legal requirement. Where your airport asks for a clear bag, that bag may already be all the liquids organisation you need. Some authorities, such as CATSA, ask you to take the bag out of your carry-on at screening, so packing it where it can come out without unpacking everything makes screening easier.
Separating wet from dry items may limit which of your belongings are exposed if something leaks. It does not prove a pouch contains a leak, and it does not stop one happening.
Step 4: Do you need a toiletry bag?
If the answer is yes, choose by structure and by what you carry. This is inference from how each format is built. Whether a specific product holds up needs product-specific evidence that this guide does not claim.
Swipe horizontally to compare all columns. Keyboard: focus the table and use the arrow keys.
| Format | Built around | Space trade-off | Check on the listing |
|---|---|---|---|
| Hanging bag | A built-in hook; often several zippered compartments and some padding | A rigid, padded shape is likely less able to flex into odd gaps | Capacity, compartments, hook design and weight |
| Dopp kit | A single- or dual-compartment horizontal pouch; construction varies widely | Box-shaped versions are plausibly less adaptable; simple ones offer less separation | Compartments, opening style, material as the maker describes it |
| Zip pouch or pencil case | A flat, unpadded, single compartment | Lack of structure suits tight packing | Size against your kit; little built-in organisation |
| Clear liquids pouch | Visual screening; usually thin transparent material | Plausibly lower bulk than padded options | That it is transparent and meets the stated size and closure rules of every authority on your route |
Who benefits from a hanging bag. The case is strongest in shared bathrooms, hostel stays or any accommodation with limited counter space, where somewhere to hang your things solves a real problem. Outside that, it depends on whether its organisation features solve another specific need.
What you cannot tell from a listing: how well a hook holds a loaded bag over repeated hangs, how zips or seams last, whether a material resists moisture over time, and how easy a bag is to clean. Look for what the maker states and treat it as a claim.
When buying nothing is the right call
- Carry-on only, clear-bag airport. If your airport requires a clear bag, that bag already does part of the organising job. Pairing it with a small pouch you own for dry items may cover everything.
- Ultra-light packing. A lightweight zip pouch you already own may be enough.
- You own a cosmetic bag or pencil case that holds the kit. The word “travel” on a product does not add a capability your pouch lacks.
- A household resealable bag may satisfy a clear-bag requirement if it meets the stated size and closure rules. Check them first.
Before you buy
- What does your departure airport, and every airport you pass through or return from, require for liquids? Check directly.
- What do you carry: mostly liquids, mostly dry tools, or a mix that needs separating?
- Do you carry essential medicines or baby feeding items that have their own rules?
- Does something you own already do the job?
- Does your accommodation make hanging a bag useful?
- If you are buying, what specific gap does it fill?
